Problem with read.spss() and as.data.frame(), or: alternative to subset()?

Dirk Enzmann 
The selection problem can be solved by

dr2000=read.spss('myfile')
d=lapply(dr2000,subset,dr2000$RBINZ99 > 0)

however, there is still the problem that R crashes when using

d = as.data.frame(dr2000)

or

dr2000=read.spss('myfile',to.data.frame=T)

Any suggestions why? I checked whether all components of dr2000 are of 
the same length and the sort of object of each component. This is not 
the problem: Each component has the same length (9232) and there are 66 
components of the class 'character', 981 of the class 'factor', and 479 
of the class 'numeric'.
